Description
1,2-dioleoyl-sn-glycero-3-phosphoethanolamine-N-polysarcosine-25 (ammonium salt)
One promising alternative to PEGylated lipids is a polypeptide-lipid conjugate based on the amino acid sarcosine (pSar). pSar lipids of varying polymeric chain lengths have been used to tune the physical properties of LNPs such as particle size, morphology, and internal structure.
